Diagnostic value of chaperone activity of heat shock proteins 70 in coronary atherosclerosis

Abstract


Aim. The aim of the research was to study the role of chaperone activity heat shock proteins (HSP) 70 in pathogenesis and diagnostic in patients with coronary atherosclerosis. Materials and methods. We examined 354 patients with coronary heart disease, who had coronary atherosclerosis of varying degrees, according to coronary angiography (was performed by the Judkins technique). The severity of coronary atherosclerosis was determined on the basis of the Gensini index. According to the Gensini index, patients were divided into 2 groups: GS0 - 152 patients without signs of coronary atherosclerosis, GS1 - 202 patients with coronary lesions. Chaperone activity was determined by thermodynamic method. Results. The study showed significant differences in the level of chaperone activity HSP70 in patients with different severity of coronary atherosclerosis. The correlation analysis revealed a significant negative relationship between chaperone activity HSP70 and the Gensini index. The cut-off value of chaperone activity of HSP70, by which can be judged on the presence or absence of coronary atherosclerosis, is establish. Conclusion. The revealed threshold of chaperone activity can be considered as a possible marker of the severity of coronary atherosclerosis.
